    • A dual band antenna includes a first linear periodic array of first individual antennas for a first frequency band and a second linear periodic array of second individual antennas for a second frequency band. The period of the first linear periodic array is essentially twice as large as the period of the second linear periodic array. The second individual antennas are arranged alternately between the first and above the first individual antennas. The first individual antennas and the second individual antennas are embodied as patch radiators. The first and second individual antennas each include a printed-circuit board arranged in a rectangular, electrically conducting box which is open towards the top in addition to several patch plates which are arranged at a distance on top of each other above the printed-circuit board and parallel to the printed-circuit board.
    • 双频带天线包括用于第一频带的第一单独天线的第一线性周期阵列和用于第二频带的第二单独天线的第二线性周期阵列。 第一线性周期性阵列的周期基本上是第二线性周期阵列的周期的两倍。 第二单独天线交替布置在第一和第二单独天线之间。 第一单独天线和第二单独天线被实施为贴片辐射器。 第一和第二单独天线各自包括布置在矩形导电盒中的印刷电路板,除了在印刷电路板上方彼此相隔一定距离上布置的多个贴片之外,其朝向顶部开口 并且平行于印刷电路板。
